Hey, A4s…ever feel like a dinosaur? I know I sometimes do.
When I finally transitioned to an aircraft with a HUD, (which I could barely spell at the time) I found it mostly distracting (except for the radar slaved HUD bogie diamond, which made my 20-15 eyes
on a good day – and too often augmented by my sharper-eyed ROs - to about 20-5s or even better

).
However, HUD "de-clutter" was my favorite switch position.
I truly missed the days of old iron gun sights, figuring out mils, and messy grease pencil marks on the canopy…. Which nevertheless granted me some very respectable CEP's and some serious HE iron on target.
Back in the day, if somebody mentioned HUD, they only meant this……
